# QBO Error: Couldn’t export business unit “Business Unit Name”, the error: Tax code for invoice ######### is not specified.

## Problem

This error indicates you have not set a tax zone for that customer's location in ServiceTitan.

## Solution

### Confirm address and set tax zone

An address must have a zip code in order for tax zones to be successfully applied automatically through your settings:

1. For the erroring out invoice in question pull up the customer's service location and validate the address if necessary by clicking on the orange '?' next to the address. ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/qbo-error-couldnt-export-business-unit-business-unit-name-the-error-tax-code-for-invoice--is-not-specified.-image-4r5zypzh.png)
2. This will prompt you to set the location to a Google-validated address. If the address is not found or is unable to be validated, at minimum, you will need to manually enter a zip code.
3. Once the address is entered into the correct format, you will need to set your tax zones.
4. To set a tax zone in ServiceTitan, click the Settings icon. In the side panel, click **Invoicing** > **Tax Zones**. ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/qbo-error-couldnt-export-business-unit-business-unit-name-the-error-tax-code-for-invoice--is-not-specified.-image-agtis797.png)
5. Here, you can assign customers to an existing tax zone or create a new one. Be sure you click **Set Tax Zones** when you have finished.
6. On the Accounting Page, pull up the Batch with the error unpost/repost the batch > Right Click + Reload anywhere on the screen to hard refresh the page > export the Batch. ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/qbo-error-couldnt-export-business-unit-business-unit-name-the-error-tax-code-for-invoice--is-not-specified.-image-b42chyf0.png)
